/// This class represents profiling event information for a context sensitivity.
/// Context sensitivities are decisions where a particular input resulted in an
/// SLL conflict, but LL prediction produced a single unique alternative.
/// <p>
/// In some cases, the unique alternative identified by LL prediction is not
/// equal to the minimum represented alternative in the conflicting SLL
/// configuration set. Grammars and inputs which result in this scenario are
/// unable to use
/// <see cref="PredictionMode.SLL"/>
/// , which in turn means they cannot use
/// the two-stage parsing strategy to improve parsing performance for that
/// input.</p>
